SPECTACLES Filed Aug. 28, 1935 Patented Nov. 10, 1936 UNITED STATESPATENT OFFICE 2 Claims.

This invention relates to spectacles and more especially to new andimproved means for connecting the bows or temples tothe lenses.

It is an object of the invention to provide end pieces for attachment tothe lenses and so constructed that the bows or temples can be readilyplaced in or removed from position, it being unnecessary to use thesmall pivot pins or screws such as commonly employed and whichfrequently become lost.

Another object is to provide attaching means for the bows which willhold them properly while in use, said means being simple inconstruction, easy to apply and having no parts likely to get out oforder.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in certain novel details ofconstruction and combinations of parts which will be hereinafter morefully described and pointed out in the claims, it being understood thatchanges may be made in the construction and arrangement of the partswithout departing from the spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has beenshown.

In said drawing Figure 1 is a rear elevation of spectacles having thepresent improvements.

Figure 2 is a plan View, the positions of the bows when sprung toposition for removal, being indicated by broken lines.

Figure 3 is an enlarged plan view of the attaching means, the pintle ofthe bow being in section.

Figure 4 is an enlarged section on line 4-4, Figure 1.

Figure 5 is an enlarged rear elevation of the attaching means, therearwardly extended bow being in section.

Figure 6 is a front elevation of the attachin means and the bow pintletherein.

Referring to the figures by characters of reference, l designates ametal strip folded to form ears 2 and 3 spaced apart to receive the edgeof a lens L therebetween. One of the ears, 3, is folded back upon itselfto form two thicknesses, the inner thickness terminating in a smallsleeve 4 while the outer thickness is rounded outwardly at 5 to straddlethe sleeve. A screw or any other suitable fastener 6 is extended throughthe ears 2 and 3 and lens L to hold them together. These pieces may becut from any suitable metal.

Attached to or formed integral with the plate I is a retaining tongue Iwhich is spaced from the upper end of ear 3 and is set back from theplane of lens L. This tongue, which is extended laterally substantiallyparallel with the lens, is of a resilient material and is preferablyshaped to provide a recess 8 in the bottom thereof while the free end ofthe tongue is upturned as at 9.

Each bow IU of the spectacles has one end bent down to form a shortpintle II adapted to fit in sleeve 4 so as to rotate therein. When thebow is in position, that portion thereof nearest the lens will be lappedby tongue 1 and rest in recess 8. Thus it is not possible for the pintleto lift out of its bearing sleeve 4 when the bow is extended eitherbackwardly at any angle or folded against the lenses, as shown.

When swung back from the lenses, the bows will be limited in theirmovement by the downwardly projecting sides of tongues 1. When swungforwardly they will come against the lenses. When in either positionthey will be lapped and held by the tongues 1.

When it is desired to remove a bow it is necessary merely to spring itupwardly and forwardly toward and across the lens a sufficient distanceto move it from under the tongue. The pintle l I and the adjacentportion of the bow can then be lifted out of the sleeve 4 through thespace provided between the tongue and the plane of the lens. To attachthe bow the foregoing operation is reversed.

What is claimed is:

1. A strip having spaced ears for receiving a lens therebetween, asleeve carried by one of the ears, a bow having a pintle at one endinsertable into the sleeve for rotation, and a resilient retainingtongue on the strip normally overlying the bow to hold the pintle in thesleeve, said bow being bendable out of normal shape in the direction ofthe lens to release the bow and pintle for removal past the tongue.

2. The combination with the lens of spectacles, of connected ears spacedto engage opposite surfaces of the lens, a bearing sleeve carried by oneof the cars, a bow, a pintle at one end thereof insertable downwardlyinto and rotatably mounted in the sleeve, and a resilient retainingtongue connected to the ears and extending partly across the adjacentlens, said tongue being positioned to provide a space between it and theplane of the lens, the tongue overlying the bow tohold the pintleagainst withdrawal from the sleeve when the bow is in any position at orbetween its normal limits of movement, said bow being bendable out ofnormal shape in the direction of the lens to position the pintlecarrying portion thereof for movement through said space to disengage itfrom the tongue and release the pintle for withdrawal from the sleeve.
